York, Y., a Corporation of ew York. Filed Mar. 6, 1911. Serial No. 612,465. j To all whom it may concern; Be it known that I, Coacoao UITON, a :eitizen of the United States, and resident of llialtimore city, State of Maryland, have inlvented certain new and useful Improvegments in Antifriction-Bearings, of which the followin is a specification.

The object of my invention is to provide @an anti-friction bearing, simple in construc tion and ellicient in use, wherein the rolling {members will be retained in proper operating position between the inner and outer i-aceways, and will be retained in position upon one of the raceways when the other ra ee yay is removed. H

My invention comprises novel details of improvement and combinations of warts that will be more fully hereinafter set crib and then minted out in the claims.

Roierence is to be had to the tlCCt)lIl])l\ll part hereof, wherein, I roken side view of an anti-friction bearing embodying my invention; Fig. 2 is a section on the line 2, 2, in Fig. 1, and Fig. 8 is a detail looking at the inner surface of the retainer or cage for the rolling members.

The numeral 1 indicates an outer ringlike member or race and 2 indicates an inner race concentric with the outer race or moma )eripheral raceway or groove 2' receiving r0 ling members, such as rollers 3, that also bear against the raceway or wearing surface 1' of race 1. The corners 2", of raceway 2" are shown beveled to coact with the corresponding beveled edges 3' of rollers 8. Between the rollers 3 are separator rolls 4.

At 5 is a retainer, separator or on e, shown! in grooved ring-like form fitted reely between the races 1, 2. The retainer or cage, 6 has flanges 5" on o )posite sides between;

, ,which the rollers 3 an rolls 4 are fitted, the} separator rolls 4 being of such length as to; coact with the flanges 5" whereby endwise;

movement of the separator rolls is limited. .ltctainer 5 is also provided with spaced openings 5" through which the working roll-,

ways. ,The corners 5 of openings 5" are shown beveled to coact with the beveled edges of rollers 3.

10 retain the working rollers 3 upon race 2 when the outer race 1 is removed, the retainer or cage 5 is provided with projections 6 adapted to enter recesses 3" in the corresponding epds of rollers 3. I have shown tie projections 6 stamped or cut from the materia of retainer or cage 5, in the arrangement shown the projections 6 being! itheirbetween, the separator 'sponding rollers 3, whereby said parts are:

retained upon race 2; the outer member or; race 1 may then be slid over rollers 3, andt the parts assume the positions shown 1n Fig. 2. The separator rolls 4, by bearm 5 upon the annular surface 2f at the sides 0 raceway 2, sustain the retainer or cage 5 so.-

that the same may float freely around he tween races or m mbers I, l, and as rollers 2' are retained in the raceway 2" and project through the openings 5 of the retainer the f latter is kept from lateral displacement l'Clll-r. Lively in race .1. 2, may be mounted upon and attached to shafts, hubs and the like. in any well known The members or races 1,

llllllllKl'.

While I have illustrated and described a practical embodnnent of my invention, it

will be umlcrstood that changes may be, made til the construction and arrangements rolling members, said retainer being separate from said race rings and free to rotate rolls at their ends abutting the a jacent inner faces of said flanges and being free from said retainer to assume required positions between the rolling members, the annular portion of the retainer between the flanges retaining the separator rolls from outward radial displacement.

2. An anti-friction bearin comprising inner and outer race rings, rolling members I an inwardly annularly grooved retainer between said race between said race rings,
